摘要

土木工程设计方法的发展为结构的更复杂分析提供了可能。计算软件不仅对常规设计有帮助,而且对识别和解决更具体的问题也有帮助。有限元法(FEM)已成为最常用的数值方法之一。许多商业节目都是基于这种方法。然而,这些程序更复杂,需要熟练的设计师充分利用他们的潜力。本文率先将商业软件ADINA实现的有限元方法应用于结构力学问题的求解。将有限元建模的理论方法与实际问题的经验相结合是必要的。熟练的设计人员可以校准数值模型以获得相关输出。然而,在某些情况下,在设计过程中仍然需要详细和个性化的方法,并通过现场监测和观察来验证。引导学生对设计的灵活处理是教学过程中的重要任务之一。这包括对问题进行适当分析的基本知识,以便有效地利用特定应用程序的计算软件,甚至是更复杂的解决方案。

Application of the ADINA Software for Tasks of Educational and Technical Practice
Development of the designing process in civil engineering brings the possibility for more complex analysis of the structures. Computational software can be helpful for regular design but also for identification and solving of more specified problems. Finite Element Method (FEM) became one of the most used numerical methods. Numerous commercial programs are based on this method. However, these programs are more complex and require skilled designer to fully utilize their potential. This article brings the lead to apply the FEM method implemented in commercial software ADINA to solve the problem of structural mechanics. It is necessary to connect the theoretical approach of FEM modeling and experience from real case problems. Skilled designer can calibrate the numerical model to obtain relevant outputs. However, certain cases still require a detailed and individual approach during designing that is verified by the in-situ monitoring and observation. Lead of the student to the flexible treatment of the design is one of the important tasks of the educational process. This involves the basic knowledge about appropriate analysis of the problem for effective utilization of the computational software for particular applications even for more complex solutions.
